I’ve had some Sorby chisels with the boxwood handles for years. They’ve held up very well to all the misuse that a pro shop(and coworkers) gave them. I removed the lacquer and put some oil on the handles, so they are very comfortable. Made in England, so metric is available. But may be too mass produced for your liking.

You might try emailing some of the tool makers and ask if they’ll make some metric ones. Just an thought.
